Who knew Preet Bharara’s a Quentin Tarantino fan? The Manhattan US attorney stunned attendees at the DealBook conference when during a Q&A he reeled off a “Pulp Fiction” speech. “When asked about future plans, he said, ‘I’m gonna answer the way Samuel L. Jackson did at the end of ‘Pulp Fiction.’ And then he recited — from memory — [the film’s] ‘walk the earth’ speech, including the ‘Kung Fu’ reference. It was awesome!” said a spy. The lines include Jackson telling John Travolta when asked, “You’re really thinking about quitting?” as a hit man, “Basically I’m just gonna walk the earth . . . You know, walk the earth, meet people . . . get into adventures. Like Caine from ‘Kung Fu.’ ” Others at the conference Tuesday included Barry Diller, Daniel Loeb, Elon Musk and David Karp. Our spy said Bharara got a more muted response when he took the stage, but “won them over.” Perhaps attendees were relieved Bharara, who’s gone after SAC Capital and Galleon Group, didn’t use another Tarantino line, “I’m-a get medieval on your ass.”
